Introduction
The goal of this lab is to practice working with ArrayList
s by
completing a Document
class that represents a text
document as an ArrayList
of String
objects,
where each entry in the ArrayList
corresponds to a single
line of text.
This lab was designed as a command-line Java application, so you should consider compiling and executing in the terminal. As a reminder, you can follow the following steps to compile and execute a Java program in a Unix-style terminal:
cd the_directory_where_your_code_is_stored
javac File1.java File2.java ...
java File1
This example assumes that File1.java
contains the
main method for the application.

Files
The following files are provided:
Document.java UNFINISHED
DocumentTestDriver.java This is a simple driver class for testing
Document.java
. Take a minute to look over this code to get a better idea of the expected behavior.Editor.java This is an editor application that provides a command-line interface to the
Document
class.
Instructions
Download the files above and complete Document.java
so that all methods conform to the Javadoc comments. Test your completed
file by running the two provided application programs.
Your solution should use only enhanced for loops.
Submitting
Submit your completed version of Document.java
through Gradescope . You have an unlimited
number of submissions. If you have trouble with your submission, you
may find it helpful to look at the JUnit submission tests:
